CARRIAG E-DOOR LOCK.

SPECIFICATION formingpart of Letters Patent No. 695,335, dated March 11, 1902-.

Application filed November 29,1901. Serial No. 83,964. (No model.)

To coZZ whom it may concern:

Be it known that LANroN OOHSNER,0E New Haven, in the county of New Haven and State of Connecticut, have invented a new and usef ulImprovementin Carriage-DoorLocks; and I do hereby declare the following, when taken in connection with the accompanying drawings and the figures of reference marked thereon, to be a full, clear, and exact descrip tion of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a view of a carriage-doorlock constructed in accordance with myinvention and showing its cover removed; Fig. 2, a view of the lock on the line a b of Fig. 1, but with the cover of the lock-casing in place.

My invention relates to an improvement in carriage-door locks of the class designed to be applied to the outer pillars or posts of such doors rather than to the framed portions or bodies thereof, the object being to produce a simple,durable,elfective,and convenient lock, which will not rattle nor become deranged and which will not wrench the wrist when the door is swung to with the hand grasping either the lever-handle or the rotary or knob-handle of the lock.

With these ends in view my invention consists in a lock having certain details of construction,as will be hereinafter described,and pointed out in the claims.

In carrying out my invention I employ a lever-handle 2, which swings upon a heavy hub 3, located within the lower portion of the narrow upright locking-case 4. In order to adapt this casing to be located within a mortise formed entirely Within the outer pillar or post of a carriage-door it is necessarily made in a narrow upright form and as compact as possible, whereas in looks designed to be applied to the framed portions or bodies of carriage-doors the casing may be made larger and more nearly square. When the lock is in place, the handle end of this lever-handle extends upward on the inside of the carriagedoorand provides for retracting the latch-bolt 5 by what amounts to a direct pull, though as a matter of fact the handle swings in a slightly-curved path instead of moving in a straight path. The said handle is formed with an upwardly-proj ectin g inwardly-curved arm 6, engaging with the inner edge of an operating-lug7,depending from the bolt 5,\vliich, as shown, is formed with a longitudinal recess 8 for the reception of a guide-rib 9,formed upon the lock-casing 4:. A spiral spring 10, encircling a stud 11, located in the upper part of the said locking-case and above the said bolt 5, engages with an arm 12, projecting upwardly from the bolt which the spring constantly urges into its locked or projected position. I also employ a roll-backlocated between the said bolt 5 and the hub 3 of the lever-handle 2 and consisting of a hub 13 and an arm 14:, extending upward therefrom between the flange 4c of the lock-casing and the inner edge of the arm 6, through the medium of which the roll-back acts in retracting the bolt. The said hub 13 is reduced in diameter at its ends to form short trunnions 13 13, by means of which it is journaled in the lockcasing 4 and in the cover 15 thereof,as shown in Fig. 2. It is also formed with a square openin g 16, receiving the spindle 17 of a rotaryhandie 18, which may take the form of a knob and which is rotated for turning the roll-back, so as to unlock the door. Anantirattling-spring 19, secured to thelever-handle 2 and engaging with a pin 20, mounted in the lock-casing, provides for preventing the lever-handle from rattling, which it might otherwise do should thebolt itself be prevented from any cause from taking its normal fully-projected position in which it holds the lever-handle against rattling by the engagement of its lug 7 with the arm 6 thereof, as shown in Fig. 1.

Under the construction described the operation of the lever-handle does not disturb the roll-back, and therefore does not turn the rotary or knob handle, for the reason that its arm 6 simply moves away from the arm 14: of the roll-back. On the other hand, when the rotary or knob handle is turned the lever-handle is simultaneously operated and to the same extent, because the arm of the rollback acts upon the bolt only through the medium of the arm 6 of the lever-handle; but when the carriage-door is sharply closed and the bolt forced by engagement with its strikeplate (not shown) back into its unlocked position neither the lever-handle nor the rotary or knob handle are disturbed, which is very desirable, as on that account a carriage-door provided with my improved lock may be closed either from the outside orfrom the inside with the hand upon the lever-handle or knob-handle, as the case may be, without the wrench to the wrist, which would otherwise follow the sudden movement of either handle with the forcing back of the bolt by slamming the carriage-door. I further wish to point out that on account of the construction of my lock it requires a comparatively thin case, and therefore necessitates the minimum cutting away of the carriage-door in order to provide for its accommodation therein.

I would have it understood that I do not limit myself to what I have shown, but hold myself at liberty to make such departures therefrom as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a carriage-door lock, the combination with a narrow, upright casing adapted to be located in the pillar of a carriage-door, of a latch-bolt, a latch-bolt spring located above the bolt, a lever-handle pivoted below the bolt and extending up under the belt for coaction therewith, and a roll-back: located between the bolt and the pivot of the lever-handle and acting on the bolt through the medium of the said lever-handle which itself acts upon the bolt independently of the roll-back, the said bolt being free to be pushed back without disturbing either the lever-handle or the roll-back and the lever-handle free to be operated for the retraction of the bolt without disturbing the roll-back.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
